Related Products of 14804-31-0,Some common heterocyclic compound, 14804-31-0, name is 4-Bromo-1-methoxy-2-methylbenzene, molecular formula is C8H9BrO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: To a solution of compound 1a-e (10.0 mmol,1.0 eq) in anhydrousTHF (20 mL) was slowly added n-BuLi (6 mL of 2.5 M solution inhexane, 15.0 mmol, 1.5 eq) at 78 C. The mixture was stirred for1 h and triisopropyl borate (50.0 mmol, 5.0 eq) was added by syringe.The solutionwas stirred for another 1 h and allowed towarmto 25 C overnight. The reactionwas cooled to 0 C, followed by thesequential addition ofwater (5 mL) and 2N HCl (5 mL). After 10 min,an additional 35 mL of 2N HCl was added and the mixture wasfurther stirred for 30 min. The mixture was extracted with ethylacetate (20 mL * 3) and the combined organic layers wereconcentrated to a thick oil under reduced pressure. Crystallizationwith cold hexane yielded a white solid.
The synthetic route of 14804-31-0 has been constantly updated, and we look forward to future research findings.
